Now that the chrome process is a singleton on all platforms, we can safely add a cache to the CookieJar to greatly speed up access. The way this works is we read all cookies upfront from the database. As cookies are updated by the web, we store a list of "dirty" cookies that need to be flushed to the database. We do that synchronization every 30 seconds and at shutdown. There's plenty of room for improvement here, some of which is marked with FIXMEs in the CookieJar. Before these changes, in a SQL database populated with 300 cookies, browsing to https://twinings.co.uk/ WebContent spent: 19,806ms waiting for a get-cookie response 505ms waiting for a set-cookie response With these changes, it spends: 24ms waiting for a get-cookie response 15ms waiting for a set-cookie response
